Rising carbon dioxide levels are increasing extreme weather events in Australia, report finds Science | Instant News

Australia’s climate has entered into a new era of sustained extreme weather events, such as bushfires and dangerous heat waves, thanks to rising average temperatures, according to new reports by two of the country’s government climate science agencies.

Rising levels of carbon dioxide in the atmosphere, mostly from burning fossil fuels, have triggered even more dangerous bushfires, rising sea levels, and a rapid rise on days when temperatures reach extreme levels, the Bureau Meteorology and CSIRO said in Australia’s latest State of the Climate Report.

“What we are seeing now is beyond the reach of what was possible before,” said Dr Jaci Brown, director of the CSIRO Center for Climate Science.

While 2019 is the hottest record in Australia which helped fuel unprecedented wildfires, these temperatures will appear to be average once global warming hits 1.5C, the report said.

Among key findings, the report said Australia’s climate had warmed 1.44C since 1910 with the season of wildfires getting longer and more dangerous. Australia’s oceans have warmed to 1C and are acidifying.

In a briefing to reporters on Tuesday, Dr Karl Braganza, manager of the agency’s climate prediction service, said conditions in Australia were in line with projections over the past several decades.

But he said: “What we’re seeing now is a more pronounced shift to the extreme and we’re starting to feel how that shift in averages impacts extreme events.

“So we don’t feel the average temperature rise of 1.44C, but we did feel the heat wave and we felt the fire weather.”

Between 1960 and 2018, the report said there were 24 days when the country’s average maximum temperature reached 39C or higher. But 2019 alone has produced 33 such days.

Australia’s long-term greenhouse gas monitoring station at Cape Grim, in Tasmania’s northwestern tip, shows levels of CO2 accumulating in the atmosphere at an accelerating rate.

From 1980 to 1989, the amount of CO2 increased by 14 parts per million, but in the decade ending 2019 it increased by 23 parts per million.

Brown said that although the global economic slowdown due to the Covid-19 pandemic has led to reduced emissions, this is just a blip.

“Another way to think about this is if you’ve been eating junk food for 10 years and then you go on a diet for one day and jump on the scale the next morning and expect to see some change or decrease in dress sizes. It’s not that simple. It’s about long-term change, “he said.

“The big challenge for our children and grandchildren is how to flatten this curve.”

Emissions from fossil fuels – coal, oil and gas – are a major contributor to the growth of CO2 in the atmosphere, said the report, and were responsible for about 85% of emissions from 2009 to 2018.

Rising ocean temperatures, ocean heat waves and acidifying waters are also projected to continue, posing a significant threat to Australia’s coral reefs, Brown said.

Since 1970, rainfall in southwestern Australia has fallen by about 16% in the colder months between April and October, but much of northern Australia has seen an increase in rainfall.

The river flow meter also shows less water flowing through rivers in the southern part of the country since 1975.

“Australian agriculture is already facing significant challenges and disruptions from climate change, seen through record droughts, heat waves and rising temperatures,” Dr. Michael Battaglia, CSIRO director of agricultural and food research, said.

“The effects are widespread, affecting food production, supply chains, regional communities and consumer prices. Our farmers are resilient and capable, but climate change exposes them to significant risks. “

Australia’s temperature projections in the next two decades show each year to be warmer than “in a world without human influence”.

This, says the report, is known as the “emergence of climate change”.

While the current decade is warmer than any other decade over the past century, the report says it will likely be the coolest decade of the next century.

Australia will experience further warming, more very hot days and less cold days. The incidence of extreme heavy rain will also increase.

There may be fewer tropical cyclones in the future, the report said, but the cyclones that form will be more likely to become more intense.

Brown told the Australian Guardian that while the findings in the report were “contradictory”, it showed that “now is the time to act.”

The report’s release comes as the prime minister, Scott Morrison, faces pressure to keep up with major trading partners and tying Australia to net zero emissions targets by 2050.

Climate-stricken countries say survival depends on strong 2020 action | World | Instant News

BARCELONA – Developing countries risking wilder weather and rising seas on Wednesday urged all governments to meet deadlines to deliver stronger national climate action plans to the United Nations by the end of 2020, stressing that their survival depends on it .

Some 195 countries committed under the 2015 Paris Agreement on climate change to submit an updated plan this year, with the aim of increasing pledges so far inadequate to curb planetary warming emissions and adapt to the effects of warming.

But the health and economic crises caused by the COVID-19 pandemic have knocked climate diplomacy off course and forced the postponement of this year’s UN climate summit to November 2021.

Nonetheless, the effects of the pandemic should not be an excuse for countries to shy away from submitting a more ambitious national plan to combat climate change, said Ethiopian President Sahle-Work Zewde.

“Both challenges – climate change and COVID-19 – can be overcome in a green recovery,” he said at an online event that launched a campaign to push for the plan at the end of the year.

“Moreover, a delayed response would be costly and irreversible,” he added in the video commentary.

Zewde and several other leaders from 48 countries in “Climate Vulnerable Forum,” including Cambodia and Nepal, say they are working to submit their own latest plans this year, even though they have contributed little to planetary warming.

The Marshall Islands, Rwanda and Vietnam have done it do it.

The luxury of time ‘has long been wasted’

Patricia Espinosa, UN climate chief, repeated calls for all countries to comply with the 2020 deadline.

Doing so is “important” because no time is wasted on stepping up efforts to limit global warming to the strictest Paris pact target of 1.5 degrees Celsius, he said at the event.

The world is already warming by more than 1C from preindustrial times and is bracing for near-3C warming, even if the promises to cut emissions made so far have been met.

“The luxury of time has long been wasted – we are now only minutes to midnight,” Espinosa said.

But he added that the momentum is increasing, with about a dozen new plans having been submitted and many other countries saying they will do so this year.

The United Nations and Britain, hosts of the pending COP26 climate summit, are hosting virtual events from December 12 to marks five years since the Paris Agreement sealed, giving leaders a platform to show off their enhanced plans.

Bangladesh Prime Minister Sheikh Hasina, whose country currently leads the CVF, pointed to the efforts – and investments – being made by member countries to reduce emissions and adapt to climate change within their borders.

In Bangladesh, for example, scientists have developed crops resistant to salt, floods and drought, as well as floating agricultural technology, while Costa Rica produces 100% renewable electricity for most of the year, he said.

Ethiopia planted more than 5 billion tree seedlings during this year’s rainy season, leading to 20 billion by 2022.

But a “strong international partnership” remains necessary for vulnerable countries to minimize the “huge losses and damage” caused by the effects of climate change such as worsening floods, storms and higher seas, Hasina added.

The window of opportunity closes

CVF member countries, representing more than 1 billion people in Africa, Asia and Latin America, expect the G20 countries – which account for more than three-quarters of global emissions – to produce “clear and definite” plans to effectively cut those emissions, he says.

He also urged rich countries to keep promises to raise at least $ 100 billion a year from 2020 to help poor countries develop cleanly and adapt to a warming planet.

David Waskow, of the World Resources Institute, said action on climate change was urgent but “what matters in the end is the level of ambition,” especially from big emitters like China.

Espinosa said that if countries put forward action plans after the 2020 deadline, they would not be included in the February main report that synthesizes progress towards Paris’ goals of keeping warming to “well below” 2C and ideally up to 1.5C.

The next official filing date for a stronger plan, under the Paris agreement, is five years away, he added – “at which point, our window of opportunity (to achieve our goals) may close.”

Travel together in the labyrinth of life by enlightening each other | Columns | Instant News

How do you deal with the loss? Not just the loss of a loved one who has filled your life and haunts your dreams – we all face this at one point or another, and we struggle with a helping hand, a offered shoulder, a sharing of the burden. . Either you come out on the other side and continue, or you don’t; Either let it overcome you or you persevere. It’s an experience as common as sunrise, as painful as amputation, as nostalgic as memory, as universal as breathing, but that, in a way, seems different, how to deal with the loss of icons , social norms, of a world so familiar that its disappearance seems disorienting and just plain wrong? Daily life is like this now. Beloved faces have vanished from our sockets, some by death, some by the estrangement that this pandemic demands. Our worlds are small, limited to home and home. Our circles have shrunk to coin-sized spheres, bounded by windows and walls, and the closest ones that are not sick. Those who are sick are beyond our reach, even for a farewell hug. protests, violence, deception, unreliable governments and unsympathetic politicians – making our forays into the outside world gruesome enough to bring us back inside, into our cocoons. A presidential campaign as a source of division, rage and brutality as anyone in living memory burns families in internal alienation. An angry, hostile, unrecognizable national atmosphere offers no comfort; instead, it shocks with a slap like opening a door in Dante’s Hell.Some struggle with hunger, eviction, job loss, uninsured illness, lifelong disabilities caused by COVID, death. Others, in addition to everything else, still face the age-old and weary reality of racial injustice, a kind of pre-COVID virus that has always made leaving home risky for some. Forest fires are rampant so that our wild places and entire cities are vanished in the blink of an eye. Century-old storms hit our shores in what seems like once a week, flooding and pounding as Mother Nature unleashes her fury at the way we treat her. (If only we could coordinate the torrential rains to put out the forest fires…) Add to that the passing of those who inspired – Ruth Bader Ginsburg, John Lewis, Chadwick Boseman – and those who served – medical professionals, first responders – and there doesn’t seem to be an end to the heartbreak and despair. No matter what your race, your gender, your age, your political affiliation, your religion, your financial situation – each of our Americas, each of our little worlds, is dark and unrecognizable. So how do you survive? How do we persist? How to emerge uninterrupted, without bitterness, strong? We can discuss who is responsible for our national situation. We can blame and call for retribution – and eventually we probably will, it’s human nature. We can point fingers and demand revenge. We can assess and rebuild, reflect on what went wrong, and try to better prepare ourselves for such future times. But it’s for tomorrow, today we’re fighting. We share. We elevate. Today, we are looking for common ground. We suffer together, despite the quarantines, so we must survive together. We recognize that this planet, in the grip of present pain, is the only vessel we have to inhabit, and that the death of one creature diminishes the life of all. So we reach out. We embolden the best angels in our nature and stifle those impulses that pit us against each other. We examine our souls to see what is right, what really matters, what is gold and what is slag. Then we act, we look in the shadows to see who endures silently, in the darkness, so that we can lean in, reach out. We look for gaps that we are able to fill and intervene without hesitation. We rise up, all humans, and love each other on a scale never seen before, for it has never been so critical. We remove the blinders, shift the prejudices of the past, reject lethargy and welcome challenges – for this is our only path. We recognize that overcoming what we face today will shape and make possible a world in which we rejoice tomorrow. COVID-19, global warming, tyranny, and division – these are all symptoms of the deeper diseases that threaten our planet: the diseases of ignorance, “otherness” and narrow-mindedness. But joy can come in the morning, after this long night of pain, if we walk through this labyrinth together, enlightening each other. The return of violence for violence multiplies violence, adding a deeper darkness to an already starless night. Darkness cannot come out of darkness; only light can do it. Hatred cannot drive out hatred; only love can do it. These are the words of Martin Luther King, over half a century old. We must remember this. We will right the wrongs and undo the damage when a bright future replaces this living nightmare. For now, we have to love. Everyone. Because everyone is suffering, and everyone deserves what humans are uniquely qualified to give. Today we demand that we reject all excuses for being less than what we can be; today demands that we stretch out to adapt to the times, to recognize our pettiness for the evasion that it is, to rise above it. We have to care about it, with our whole being, because there is no other way. And we have to resolve that as we have all shared the agony, we all have to share the joy that comes in the morning. We have to see it. It will be the reward of perseverance – a better country, born out of this baptism of fire, or else the purifying flames are wasted. As new shoots line the wildfire desolation, new trees will grow as a result of the blaze. We have to push back, after that, our burn. And we go. Because We Can.

It’s a strange time to travel | To select | Instant News

Next week we will be in Pennsylvania to visit our daughter who is at school in Erie on Lake Erie This will be one of our most unique trips as face masks are needed for almost the entire trip . Traveling is just not what it used to be. Do you remember when people smoked cigarettes in the middle of the flight? A little light came on to tell the passengers it was time to put out their cigarettes, we were going to land. Smokers who flew on the plane at the time were very upset when new rules banned smoking on board. I have a feeling these same people would be really unhappy with the requirement to wear a mask for the entire flight We received an email reminding us that anyone over 2 years old must also wear a mask at airports except when we were We were also told that we would receive an “ all-in-one ” snack bag that included a wrapped disinfectant wipe, an 8.5 ounce water bottle and two snacks, as well as a sealed drink on flights over 2 hours and 20 minutes. “On flights shorter than that, we’ll have a sealed drink and that’s it. No more friendly flight attendant taking our drink order. Erie is quite close to Niagara Falls. We were wondering if we could see it or not, as people like to go to the Canadian side for a better view, and the border between the US and Canada is closed at least until the end of August. which is the boat that takes you near the falls, was closed in June, it is now open on the US side and available for people in good health, wearing masks and willing to stand at least 6 feet from other people on a small boat .Fort Niagara opened in July and is available for healthy masked visitors, which is the same for all the restaurants we stop at. There won’t be any buffets though, and it looks like food “that requires minimal preparation” will be the rule. Fortunately, Pennsylvania is not on the list of states that require a 14-day quarantine when we arrive home. We were also assured that the plane is cleaned within an inch of its life and that airports will be cleaner than our homes. Still, we have small containers of disinfectant to use liberally when we feel too far away from a sink and soap, and we’ll avoid other people like the plague. our face, and white where the mask was. It’s a strange time to travel. .
